AMOS W. FOX, OF NEWTON, IOWVA.

STOVE-PIPE JOINT AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 371,052, dated October 4, 1887.

Application filed January 4, 1887. Serial No. 223.412. (No model.)

To all whom it may concern:

Be it known that I, AMos W. FOX, a citizen of the United States of America, and a resi' dent of Newton, in the county of Jasper and State of Iowa, have invented a Stove Pipe Joint, Damper, and Ventilator, of which the following is a specification.

My object is to provide a simple and efficient means for regulating the draft of a stove, the temperature of a room, carry off vitiated air from the room, to save fuel, and prevent soot and gas from escaping from the stove or pipe into a room.

My invention consists in the construction and combination of a damper and ventilating device with a stove-pipe section, as hereinafter set forth, pointed out in my claims, and

illustrated in the accompanying drawings, in which Figure l is a sectional view of a stove-pipe and my device combined therewith. Fig. 2 shows my complete invention connected with a stove pipe and a range as required for practical use. Fig. 3 is a section of a stove-pipe prepared as required for attaching my ventilating device and damper.

A represents a section of stove-pipe of common form, provided with a circular opening, B, at the point where a branch or ventilator is to be attached. In place of making only one circular opening, I prefer to make segmental openings, as clearly shown in Fig. 3, to allow a deflector, c, to remain in the center for the purpose of preventing the products of combustion from entering the branch fixed over the, openings.

D is a branch pipe and ventilator fitted over the opening B, and fixed thereto by means of a fiange and rivets, as shown in Fig. 1, or in any suitable way to produce aneat and tight joint.

f is an annular chamber and enlargement near the outer open end of the branch D, that extends at right angles from the stove pipe section A. This annular groove or chamber may be produced by means of dies in the manner stove pipes are grooved and beaded; or it may be formed separately and attached in any suitable way. A receptacle for soot or dirt of any kind that may be drawn out of the stovepipe into the branch is thus provided near the outer open end of the branch to prevent it from escaping into the room.

9 is a damper pivoted in the branch D in rear of the annular chamber f, and provided with ajointed handle, h.

m is an open-ended ventilating-tube fixed to the branch D in rear of the damper g, and extendedtowardthefloor. n representsadamper in the tube m, by means of which the tube can be closed at pleasure. One or more of these auxiliary ventilating-tubes may be connected with the branch and extendedin any direction and any distance desired to convey vitiated air from a room into the stove-pipe'to be car ried off through the pipe and chimney.

Opening the dampers g and n checks the draftin the stove, diminishes the consumption of fuel, and allows the vitiated air in the room to pass through the branch D and tube m into the stove-pipe. Closing the damper increases the draft. A simple means is thus provided that can be readily applied and operated to regulate the fire, the temperature of a room, and also ventilate a room as required to maintain a pure and healthy atmosphere.

I claim as my invention-- 1. An open-ended branch pipe, D, having an annular groove or chamber,f, and a damper, g, in combination with a stove-pipe section, A, for the purposes stated.

2. The combination ofa branch pipe, D, having an annular chamber, f, a damper, g, and a stove-pipe section, A, having a series of openings, B, and a deflector, o, to operate in the manner set forth, for the purposes stated.

3. The combination of an open-ended tube, m, having a damper, a, with a branch pipe, D, having a damper, g,.and a stove-pipe section, A, having an opening, B, to operate in the manner set forth, for the purposes stated.

4. A draft regulator and ventilator comprising a stove-pipe section, an open ended branch extending at right angles from the said section, a damper in said branch, and an annular groove or chamber near the end of said 5 branch, to operate in the manner set forth.
